4.2.5. IEEE 802.16e-2005<br />
In 2003, the 802.16 st<strong>and</strong>ard group started another mission. The TGe began to combine<br />
mobility <strong>and</strong> BWA together. The result was IEEE 802.16e <strong>and</strong> it was formally published in<br />
February 2006. This st<strong>and</strong>ard introduces scalable OFDMA in PHY-layer <strong>and</strong> modi<strong>fi</strong>es the MAClayer<br />
for supporting high speed mobility. The goal is to support end users moving in cars <strong>and</strong><br />
giving them the ability to access the BWA <strong>wi</strong>thout any problems. It has backward compatibility<br />
<strong>wi</strong>th IEEE 802.16-2004. Because <strong>of</strong> its mobility, it is also referred to as mobile-WiMax. [49][50]<br />
